Hi all,
Happily listening to music with Core Player on the TP2 I received last Saturday and the phone lit up with a message from Core Player that it wanted to update my media library, following the removal of the SD Card.
Suffice to say, I was confused: no chance with the SD card hidden under the battery cover that it could have been loose and fallen out but checking through File Manager on the phone, the SD card can't be seen at all.
Put said card into an adapter and then card reader on my PC; it comes up to suggest there is no card inserted: put the same card via adapter into my digital camera and the camera refuses to even turn on with the card in.
It's a duff card I'm sure - bit peeved since it wasn't that old but meh: don't trust all eBay sellers selling 'genuine' SanDisk products I guess - however, whilst I await the arrival of a new one, could it be my TP2 that has damaged the card in some way? Has anyone else noted problems with the TP2 and higher capacity SD cards?
FlashROM based cards only have a certain number of writes. Same goes for SSDs. They should have a way to track number of writes to cards. I've had official Sandisk cards go bad on me within the first year too. Don't forget that static shocks from your clothes can actually damage the card. Also don't forget that your phone can corrupt your data if it's in the middle of a read/write op and you remove the card.

Thanks for your thoughts mate: it wasn't removed from the phone and the phone only had CorePlayer running on it at the time - so I don't think it was anything I'd done
I think I got duped by someone on eBay selling a 'Geninue' Sandisk card that perhaps wasn't - I've read here than Danetec are also quite good so I've ordered one of them directly: fingers crossed I have more luck with my second one!
I was more concerned with it possibly being my phone - I read a month or so back on the Diamond2 forum that 16GB cards didn't work so well with that phone and wondered if any forumites here had noted any issues with the TP2 and certain SD cards, thats all...
it happened to me last weekend, due to an automatic update of go news touch which went wrong.
no way to see or format the card on the ppc or my netbook. I had to go back home, put it into a usb adaptor, and finally format it with mu desktop pc. my little cer netbook couldn't detect it, and locked up each time I tried formatting it, even from cmd console. but on desktop with adaptor it went just fine.
hope you'll be able to resolve - my sandisk card was 20 days old, 65€ worth, and having it toasted isn't something I would wish to anyone

In this case, it's not even recognised - via a card reader, active sync or inside another device: this one I think is lost Meh, it's only money
Hi All
Paulplex, don't feel you are alone, this happened to me too with a genuine Sandisk 16gb card. It worked last thing at night, went to access it in the morning and it was dead - just 3 months old with no issues at all up to that point.
The solution was replace it as it would not recognise via a reader in the pc either - completely useless....
The cause? Who knows, i do suspect the TP 2 though as i had no issue with it on my old Dopod 838 pro for the first 2 months since new.
Cheers

I have read so many articles and some of them conflict with each other. I was hoping to get this cleared up. It is my understanding that the windows phone won't have removeable storage like the other WM, android, etc phones do. But I was also told that if the manufacturer designs it, the sd card internal can be replaced but when you do so you will lose all of your data and settings. Is this correct? If so, then you could put a larger card in before you setup your phone and then you would have room for multimedia and you don't have to worry about losing everything. Can somebody clarify this for me?
Technically "yes". But until some actual phones are on the market, it's very hard to answer.
However, the only data you'll only have local copies of on the SD card, is your multimedia (music) data. Everything else, including settings, will be "in the cloud", so it's not a real issue to reset the phone.
But again, we need information about the specific hardware releases for the public, before the subject can be 100% clarified.
Thanks for the info. That is what I was wanting to know. If I am going to use the phone as my pmp device as well, I will need the storage for my audio/video.
I believe they are supposed to have a minimum of 8gb of storage. This is supposed to be one of the areas that OEMs are supposed to take advantage of to differentiate their products. Give their handset appeal by tossing in a 64gb sd card.
I'm not seeing a reason you wouldn't be able to pop it open to put in a bigger card, but doing so will most likely void the warranty on the phone.
It will vary. Some will probably use internal microSD cards while others will use discrete memory chips. The minimum is 8gb. If the manufacturer does use a SD card, it is unknown how easy it will be to replace. I've seen text in the resources in the emulator saying that you must replace the original card that came with the phone. We may have to come up with a utility that formats the new cards in the way the phone needs.

So I was in the same boat you are in. Nothing could read the card except for my Nokia n97 mini. It recognized the card as "locked" and prompted for a password. I bypassed the prompt and went to the file manager. From there it let me format the card and it is back to normal. See, Symbian is good for something after all!
PS: I tried the same process with an E71 and had the same successful results. All recent Symbian phones should work as it appears they can handle the encryption and password. The card is now happily back in my HTC EVO.

This is the best news of the day .
one downside: you need a symbian phone .

There are some people reporting that if you replace the sd card of your WP7 phone and then want to use it again for your pc it isn't reconsigned any more .
this mean that you can not use it and you can not format it (for the time being it is bricked )
lets hope someone knows a way to fix it .
edit : maybe it is wise to make this sticky for a view weeks .

correct. Once the card is formatted for the phone, it can only be used with the phone.
Huh? You cant even format it after using it on the phone? Maybe Windows will fail to format it but there has to be a way to get it formatted again. They can't brick your card.

No , you can't format the sd card any more after using it in your phone .
you can only use it on your wp7 phone .
and that could be real expensive if you brick your class 6 32GB sd card .
More than likely there will be an app or tool to fix this in the short run. Never say never around XDA.

That would be my first guess.
I guess what is surprising me is for how long the phone has been in preview and in devs hands, why in the hell are so many features that are probably in the phone or are questioned to be in it, not being found already? God the first thing I do when I get a new gizmo is to search every nook and cranny of every option and setting. A good example is this and how NOBODY has tried it yet with a replaced microSD from an HD7, and how long it took for somebody to find a way to add your own ringtone. (Its right there in the Zune Hub!?! Who Knew!?!) lol
Seriously If I had a device at any point before/at the release, I could have easily found answers to a lot of questions that have been asked. Sadly with real life not landing me a job as a website tech reviewer or dev I get pushed to the back of the line. Not to toot my own horn but I really do feel like a fairly high quality QA person. I may not be able to write my own code, but I can poke and play with yours till I find all the bugs and all the features.
Anyone with a loner HD7 wanna throw it my way for test and analyzing purposes until I can get my hands on my own Sprint HTC 7 Pro? I can probably provide some really useful feedback and quality video that could easily rival a lot of these sites.

The reason is because it hasn't released to the USA yet. I have noticed that other areas lack the adventurous spirit.
I'm excited to see what will come after Monday.

Little bit off topic, but I consider my self to be a fiddler trying to find out every little option. I truely cannot find anything in zune on how to set ringtones?!
Where!? and How?!
In the tech video somewhere a day or 2 ago the guy said the option was within the zune hub. Of course no showing or saying how. Is there not a longpress on a song or the 3 dots option anywhere you can see?
Sitting stuck in the US really stinks. I wish Microsoft would give me a dang job lol. Need to get in touch with some more contacts.
That's because the setting doesn't exist. You can only use the ringtones that are on the phone right now.

Exactly. Geez, why are people refusing to believe this, it's a well known fact that at the moment you cannot set your own ringtones.
As for replacing the SD card in a HD7, been there done that. Works great, however HTC's WP7 hardware really sucks, so unless you're a diehard fan (or get them free) go with Samsung or LG. LG is actually the better choice in many aspects (just not, unfortunately, when it comes to hardware/feel).

Ok XP can only see one partition on a removable USB but if change the USB driver to a fixed disk driver then XP will see it as a hard drive then we can have lay down multiple partitions as we like. Now open regedit and goto HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Enum\USBSTOR
and double click on USBSTORE and you see a subkey below it, select the first subkey below USBSTORE and right click and select Copy Key Name
Here is mine, yours maybe different.
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Enum\USBSTOR\Disk&Ven_Generic&Prod_ USB_Flash_Disk&Rev_0.00
Now we need only need this part:
USBSTOR\Disk&Ven_Generic&Prod_USB_Flash_Disk&Rev_0.00
Copy and paste it temporarily into notepad.
You will now need this driver. http://www.xpefiles.com/viewtopic.php?t=92
Unpack it to a folder on your desktop. Inside the folder is the file cfadisk.inf. You need to open this file and scroll down to you see the line %Microdrive_devdesc% = cfadisk_install, specific data
Now you need to replace all lines %Microdrive_devdesc% = cfadisk_install, specific data with
the line you copied from your registry like so.
%Microdrive_devdesc% = cfadisk_install,USBSTOR\Disk&Ven_Generic&Prod_USB_Flash_Disk&Rev_0.00
There could be more lines so replace all and save the file.
Goto Device Manager and click on disk drives. You see your USB listed, dbl click on it and goto the driver tab and click update driver and install from a specific location and choose the driver to install and click on Have Disk and browse to the cfadisk.inf file your modified driver on your desktop and force that to replace your existing driver. It might ask you to reboot. You should now have your USB showing as Local Disk

I used this to make more partitions on a usb stick , maybe you can use this to make a local Disk of it and then make a new partition on it .
unfortunately I do not have XP anymore but diskpart under windows7 does not detect the media itself so it cant do a diskpart in the first case.
Its like the media does "not exist" anymore.
I really don't want to throw away my 16GB and my 32GB card and am still trying out solutions here.

The SD card cannot be reused to prevent piracy and information threft.
If you have business information on you SD card (say, emails, PPT/Word/XL documents), you don't want anyone to be able to just remove the SD card and use it in another phone. It's well known that WP7 uses a Raid-like setup for storage to show SD+Internal storage as one continuous unit.
Why people think you'd be able to just remove the SD card and view it in another computer/phone is beyond me... It's like common sense has gone AWOL these days...
Making the card unreadable improves security. Perhaps this isn't a big deal to many, but until you have a phone stolen/lost with confidential infromation on it, you don't know what it feels like to know that the informatin is safe and inaccessible to others.
Also, it's totally random which SD cards will work correctly in WP7 devices. The cards that do work are only shipped in bulk (to manufacturers, most likely), and aren't available for consumer purchase.
It's totally possible that a card may work right now, but as it ages it will start to fail and you will be forced to remove it.
Paying $200 for a 32GB Class 6 card right now isn't even worth the risk.
SD Card Size and Class has nothing to do with compatibility. It has more to do with random read/write speeds, which aren't the same as the card's throughput (i.e. Class).
That is probably why there aren't ay 32 GB WP7 devices available at the moment. If you want more storage you can either:
1. Buy a 16GB device and deal with it if it's enough for you.
2. Buy a 16GB device and wait for WP7 compatible SD Cards to become available.
3. Don't buy a phone and wait for 32GB phones are available (and maybe by the time the WP7-compatible SD cards are available and you can get up to 64GB storage).
4. Wait until a manufacturer releases a phone with 32GB+ NAND Flash Memory in it.
IMO, Microsoft should have dictated NAND Flash memory. SD cards do nothing but create support issues, and allow the manufacturers to skimp a lot (by using the lowest class cards available, among other things).

The more I read on the WP7 and its "expandable" storage the more I am convinced that MS has implemented RAID0 stripping to provide a higher bandwidth/speed increase in I/O and disregard data integrity error checking. This leads me to believe that WP7's performance on a slower media is horrendous (MicroSD cards), and without a doubt it is a cost saving for manufacturers because no one in their mind is going to pay a premium price for high capacity NAND storage.
Hello all,
My subscription to the xda-developers forums have been a one way "information stream", till now.
Offcourse it pleases me to (finally) have something of importance to share with all of you.
What i have found out is fairly and really plain simple.
I've seen a lot of postings about sd-card issues and overheating.
I personally bugged some of my sd-cards (and even sim-cards) because of this.
Secondly i assumed; well the sd-card is an external addon... what about the sim card??
i messured temperature distribution over the two "addon cards" (sim and sd)and surround hardware and i noticed that there is a wide-range of electrical impendace between different card combinations..(a combination of random choosen sim with a random choosen sd-card).
It looks to me that some combinations result in an electric impendance wich stresses the hardware and the cards it self, resulting in failures , overheating and or reboots.
My desire is fully functional with this knowledge applyed.
Reboots completely gone.. no overheating issues and no battery drain troubles.
(i have collected combinations who are not passing full boot, combinations who will not let me enter recovery, combinations who will function untill some wireless activity is generated.... etc.. etc)
The simcard and sd-card combination are to be further annalysed.. so it will result in a table of compatibility.
And for those who argue... but it always funtioned with my sim-card or sd card... i have to say;
it is an issue wich slowly but surely will overstress both of your cards (and or hardware).. and will continue to do so when you will not comply to the knowledge within this frame of reference.
Good luck.
Tim
I am genuinely intrigued.
Mind sharing some of this data?
Also, any ideas on how to identify this problem? If we could nip this in the bud...
I will share my findings, first off all i need to have a plan on how to identify the technical details of the sim cards used.
Then i need to get me some of those specific sim cards .
I am aware that (probably all) the cards i used are not free from wearing due to experimenting.
So when i am in possesion of new and untouched/unfryed cards i can make up a table.
I also noticed that when only using a sim card or only a sd-card those card should NOT warmup.
I also noticed that the hardware when not to heavily weared should sustain a (wifi/gps) stress test without any of the cards insert.
And finally the sim cards who surely will give troubles are those of the micro sim format (and i dont mean the size of the card it self)
Will be back soon.....duty calls
little edit.....
Not to forget.. it's all about electrical impendance.. so specific sim cards need to be used in combination with specific sd-cards. On how this relates to volltage tuning/regulation from within the kernel i am in the dark.
Its also true that one card can compensate for the other....
And least but also important... when hardware design is correct. .. .. ..

I suspect that you might be on the right track. I'll keep an eye out on this.
You might just win the adoration/lulz of the entire XDA community
I assume if there is interrest in this type of reflection on those issue's there will be more details comming out soon (if not by me then someone else will hijack this thought proccess with the best interest for all of us).
I can sense, in perspective to my last post, the descriptions i have given are to general to stricktly pinpoint the nail in the so called bud.
Realize that just a week of frustration about reboot's crashes and other failures on my wifes desire resulted in this little framework.
I am pleased with my findings so my wife can use her phone (you know the wife factor, right!?... it somehow stimulates!!)
And to be really honest, the temperature messures i did with my lips
The (prepaid) sim cards used where living in my deskdrawer without me knowing they were there.. till i found them... the sd-cards where not much different.
The phone has seen the fridge numerous times this week... to easilly spot the hot spots (with my lips).. and of course when flashing the numerous radio's wich actually doesnt matter at all.
thinking was done from a lazy chair.. in spare moments.
Also as soon i openend the phone i knew this was the point of no return. (it was still in full warrenty )
I know this is the right approach on this issue, because everyone can reprocude the reboot.. etc.. troubles... in respect of used sim card and or sd-card.
But when adjusting the sd-card on a random choosen sim card (or vice versa) will fix the issue.. makes me convinced this is how you and i and all of xda should approach this kind of issues.
ps..
I am now in the proccess of "killing" my HD2... to find out if i can make it fail and why...
Just a quick followup regarding heat issue's (aka power drain).
A few steps to determine/pindown the issue's resulting in heating up the phone.
1. without sd- and sim-card, the phone should function very nice.
wifi and gps should not warm up your phone excesively.
Your phone should give you a stripe/band of warmth form left to rigth just at the bottom of your screen (with your lips you should feel this band/stroke/stripe of warmth and you will distinctively recongnise a band of warmth and at the middle left side (near the navigation button)you will notice a spot of some what more warmth.
Your cpu is located at that location. Beneath the location where your sd-card is insered, there will be some warmth buildup when you insered a simcard.
2. You now can put an sd-card in your phone and turn it on again, it is advisable to use an sd card wich does not heat up your phone. It is at this point not an issue but when heating up your phone drains more power than necessary. You do the things you have done at step one.. but now you include heavily downloading and "gaming" stress your device.
Depending on the quality of your sd card and the warmth/heat production... your phone will stay cool/warmup a little / or hangs and reboots.
3. So far so good? (phone stays cool)
... then you are ready for step 3; that is removing your sd-card and putting in your sim card... turn on your phone again.. stress it over wifi 3g and gps, maybe play a game.
Your phone will be warmer than before and if it reboots you know your sim card is incompatible or became faulty with the phone.
Probably the sim card has been damaged to much during the last period of time when your phone was getting buggy
due to hardware/sd/sim card overstressing. (the specific electrical impendance's are at the root of the warmth/heating up issues due to the components (hardware/sim/sd) realtions to eachother)
This results in to much current passing trough "it". (the desire really should NOT get HOT when cards are compatible !!)
4. - replace sim card with sim card that does not heat your phone (stand alone)
- replace sd by sd that does not heat your phone (standalone)
Your done, but when all fails your hardware is probably to much damaged.. (wich i find hard to believe in ; knowing what my desire has gone through)
Eventually you can experiment with card combinations but that is a tough(but rewarding) way to approach this issue.
(maybe add some device like an gevy sim of some kind to establish (more) compatibility)
i will soon show you some nice videos of my results
And for all disbelievers.
Enable your PIN1.
HTC has shown in the past that simcard detection can easily fail without a PIN1 enabled. And I am aware of the fact that when a sim detection fails, a 3Volt stress operating level will be placed on the simcard...(and assumably doesn't turn it off )
The end..
There is something in it. With Sandisk 8GB class 4 sd card, my desire reboot in one or two minutes after entering to google maps. With 4GB class 2 kingston it's ten to fifteen minutes.
My old Desire was rebooting whenever the phone got to 35C. I got a new one from insurance, PVT4, and I'm using the same SD card and SIM, no overheating shutdowns at all. Highest temperature recorded so far has been 46C, which was in direct sunlight and playing music from Shoutcast (sat having beers with friends in the garden).
I'm unable to confirm your findings thus far.
When Im outside I keep my phone in the pocket and I use it just for texting. After some time while texting it restarts and I have to w8 some time until I can turn it on again,but my phone dont feel hot or anything. I rll hate it cuz I need to call or text some1 often and I cant do that because of this. When im at home this dosnt happen. So im just thinking,if I would change my SanDisk card to,let's say kingston,could that help? Also it takes a lot of time to move something to sd card from pc. And while charging,my phone overheats and restarts. Also does that while playing something like "shoot bubbles". It's really strange cuz it didnt used to do that. Im useing crayogen mod. When I flashed it for the first time it was perfect. But after some time it just started to act like that.(happaned with other rom's too) I tryed to wipe and reflash rom but it's just same thing.
At my college dorm, we use a certain type of lock in which we put our keys up to the lock, and it unlocks. I figured it used NFC, but I wasn't sure. Then I found this article.

I've got no clue what kind of hardware is in those locks, but I can say that it looks EXACTLY THE SAME as the locks used in my school. For me, that essentially confirmed they use NFC. I don't know who makes those locks, but my school uses the same looking handles and lock mechanism. When the card is held up to the lock, the lock flashes green. If I had to guess, the card acts as an NFC tag. When held up to the door, it will activate my card as any other NFC tag, verify it's me, and then let me in.
Using NFC on my phone, I was wondering if it was possible to do the same! From a logical standpoint (not a dev's standpoint), I would need to somehow steal the info off my card, have it stored in my phone as a usable format for the lock, and then I should be able to just hold the phone up to the lock to have it open!
You guys think this is possible? How would I go about doing it?
sorry that i don't have the answer, but i had this same idea! also wondering if it's possible.

I dont think these use the same frequency. Here in my office we use the HID Prox cards, but its not the same, the easiest way to know if you could do this is get the NFC tag reader software on your phone and try to read the card/key if it will see it I would think you might have a chance, if it doesnt see the card to read it, its not the same and you will not be able to do this.

Lol first thing I tried when reading this thread, but no go, we use the HID Prox cards to. Tried almost every NFC app in the market.

from what i've read...
doing what you're suggesting would pose a major security threat to all electronic door locks around the world. you're essentially duplicating your electronic key, which is not unlike duplicating an old school lock/tumbler key. unlike a traditional key however, this is an electronic key which means if you're able to duplicate it, you're also able to send/share it with friends around the world. in other words, we can set up a database of all the dorms / offices locks around the world and we can all have free access. doesn't sound like a pretty picture.
in reality, what our phones are capable of doing is READING the NFC tags. so if anything instead of thinking of your phone as the key, your phone can do the exact same thing as the lock, which is read the info off of the NFC tags. i know we have the ability to WRITE info onto NFC tags as well... but as others have posted there are issues of frequencies and i believe encryption which I HOPE makes this not possible for my security sake.
I'm sure if its physically possible(frequency wise) someone will make it happen. Its just like droid sheep, air crack, wifikill and the likes. Doesn't make it right but throw the technology out there and someone will make use of it.

I was able to do this with bluetooth and my Samsung Note 3 on Windows7. Got windows 10 and *poof*, it's gone as a bluetooth service. Now I'm scratching my head trying to figure out if that was a function of the BT dongle software, Dell security tools, Windows 7, or what!? A little off topic (not-NFC), but I have the same functional objective.
